A straight-forward method of optimising protein solubility for NMR.

Howe PW.

Analytical Sciences, Syngenta, Jealott's Hill Research Centre, Bracknell, Berkshire, RG42 6EY, UK.

J Biomol NMR. 2004 Nov;30(3):283-6

Abstract:
Maximising solubility is a key step in applying solution-state NMR to proteins. The 'microbatch' crystallisation screening method can be adapted to screen for protein solubility. In this approach, drops of test solutions are placed under paraffin oil in 96-well screening plates. This requires very small amounts of protein, is easy to set up and is readily automatable.

Overcoming the solubility limit with solubility-enhancement tags: successful applications in biomolecular NMR studies Overcoming the solubility limit with solubility-enhancement tags: successful applications in biomolecular NMR studies Abstract Although the rapid progress of NMR technology has significantly expanded the range of NMR-trackable systems, preparation of NMR-suitable samples that are highly soluble and stable remains a bottleneck for studies of many biological systems. The application of solubility-enhancement tags (SETs) has been highly effective in overcoming solubility and sample stability issues and has enabled structural studies of important biological systems previously deemed...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
